Information

The 3" NPT Class 3000 Coupling is manufactured from 304L stainless steel (1.4301) and is designed for high-pressure threaded piping systems. Its heavy-wall construction provides excellent mechanical strength and allows safe operation at pressures up to 206 bar.

The fitting features female NPT tapered threads on both ends, ensuring secure and leak-tight threaded connections for demanding industrial applications. Manufactured from corrosion-resistant stainless steel, it offers long service life even in aggressive environments.

Material

304 / 304L stainless steel is the most widely used austenitic stainless steel. It combines excellent corrosion resistance with outstanding formability and weldability, making it suitable for a broad range of industrial applications.

Equivalent material designations include:

  • 1.4301
  • 1.4306
  • 1.4307
  • AISI 304L

Advantages

  • Stainless steel (inox)
  • Heavy-wall construction
  • Female NPT tapered threads
  • Pressure class: Class 3000 (206 bar)
  • Excellent corrosion resistance
  • Excellent weldability
  • High mechanical strength
